"No, I've always been like this. I'm right, I'm right. Liu Yiling hurriedly replied, of course Liu Yiling at this time misunderstood the meaning of the magpie. Thinking that the magpie was still looking for trouble for himself at this time, he immediately began to defend himself.

"No, I didn't mean you. I mean these devices and liquid nitrogen. The magpie said.

"What's so strange about the things you brought to the slaughter, didn't the old five also say it before? It's just that the types are different, and it's definitely okay to get used to it." Liu Yiling said with a smile.

At this time, on the captain's panel, the danger value has decreased due to the increase, but it is not within the safe range. The lights showing the CO2 exceedances were always on the panel of the equipment, and the captain let the co-pilot control the plane.

Then he walked towards Magpie and the others.

"Is it just because of the different types?" muttered the magpie, who saw that there was an obvious problem with the filling equipment at this point. But this operation was all carried out by Liu Yiling, and at this time, Liu Yiling said that he was fine, so naturally he couldn't say anything.

The captain took out a handkerchief from his pocket and covered his mouth and nose, took a step and patted the magpie on the shoulder.

The magpie turned to look at the captain and said in English, "Captain, what's wrong?"

The captain pointed to the equipment and said: "We are at an altitude of 10,000 meters, and it is better not to use this kind of equipment that produces carbon dioxide all the time." In case, I mean in case. It wouldn't be good if the oxygen was too low and our cabin crew fainted, and besides, you don't seem to be in a good situation. These things should not have been allowed to be brought in, and I wouldn't have flown this trip if it weren't for the fact that you paid a lot of money. So you and I had better be disciplined, I think you know what I'm talking about?"

"I'm sorry, Captain, but I'll ask my friend how long it will take. The magpie said.

Liu Yiling naturally understood, and looked at the 48% displayed on the panel at this time, and was a little helpless.

Liu Yiling took a few steps back, tightened the valve, and said directly to the captain in English: "I'm sorry, so if it's not enough to wait, will I continue?"

"What do you mean, you're going to continue later?" said the captain, puzzled.

Of course, the plant had to be replenished with liquid nitrogen at all times. Liu Yiling said.

"Liquid nitrogen, are you sure you're supplementing with liquid nitrogen?" said the captain.

"Otherwise?" Liu Yiling said puzzled, at this time Liu Yiling felt that the captain was nervous.

The captain bent down and covered a small white solid with a handkerchief and said, "Are you sure that what you are adding to your mouth is nitrogen and not carbon dioxide? Liquid nitrogen is a colorless and odorless inert liquid, which is clearly solid." ”

Liu Yiling stepped forward to take the captain's handkerchief, but there was a small piece of condensation inside.

Liu Yiling put aside the handkerchief and put it into his hand, and the cold feeling made Liu Yiling immediately shake off the dry ice.

"You're not allowed to move these things at the airport anyway, are you? I'm telling you it's impossible. Liu Yiling said.

The magpie also looked at the captain at this time and said, "Our purpose is to transport the equipment safely, you can give us advice, but we will continue to do it." ”

"Really, let's not talk about dry ice or liquid nitrogen. Anyway, this kind of dangerous thing is not allowed on my flight, and secondly, I am now a well-intentioned science popularizer you scumbags. This is dry ice, not liquid nitrogen. The captain said angrily.

The magpie leaned towards Liu Yiling and said, "What should I do?"

"When the liquid nitrogen is gone, something will happen, I don't care. I'm going to add it next time it's 20 percent, but I don't know why it doesn't seem to be added. But I'm even more curious as to why this captain called liquid nitrogen dry ice. Liu Yiling said.

"What did I say? Is it the instrument that says it? Is the instrument on the plane fake? Now that the carbon dioxide is exceeded, isn't the solid carbon dioxide dry ice? Isn't that the stuff you're going to inject into your equipment?" the captain shouted angrily.

At this time, Mia also walked over and straddled between the two, gave Liu Yiling and Magpie a look, and then began to calm the captain.

The captain glanced at Mia and walked to the side with a curse.

Liu Yiling waved his hand and said in Chinese: "This old guy is crazy, no matter what, I still have to continue after the panel goes down." You can't let the contents come out and fly with us, can you?"

The magpie nodded his head and said, "Then let's wait a little more and do it, but I really think it's boring." If you don't believe me, you stand farther away and look at the ground. ”

"Greasy?" Liu Yiling took a few steps back in confusion and stood at a distance looking at the equipment.

At this point, the ground of the device was covered with small pieces of dry ice, and the mist of white flowers was rising.

"Liquid nitrogen, liquid state, dry ice solid, this ......," Liu Yiling muttered, and indeed the things in front of him were completely different from what he understood.

What the captain said, Liu Yiling walked to the co-pilot.

At this time, the co-pilot was piloting the plane, and his expression was a little embarrassed.

Liu Yiling said: "The equipment on the plane can detect the composition of the gas in the cabin. ”

"Yes, Mr. Liu. The captain, Mr. Arman, is a veteran pilot, so the requirements on board are a bit harsh. I've also looked at the dashboard, and there shouldn't be any problems with this military transport aircraft. After all, this transport plane can withstand missile bombardment, but you'd better be a little more restrained. And Mr. Arman has a slight asthma, and I hope you don't get angry with him. The co-pilot said with an embarrassed smile.

"Then have you seen what is exceeded?" Liu Yiling asked again.

"Only some of the combustibles can be checked, and the statement I see should be that the carbon dioxide is exceeded. That is, there is not enough oxygen, so Captain Arman pressurizes the cabin. The co-pilot said.

"I want to confirm with you that dry ice volatilizes to form carbon dioxide, right?" Liu Yiling said.

"Yes, dry ice forms carbon dioxide. Liquid nitrogen forms nitrogen, but it cannot be detected by the equipment in the cabin. So I'm not as arbitrary as Mr. Arman, I suspect it's a mixture of dry ice and liquid nitrogen. I've seen reports that these two gases can coexist in perfect harmony. The co-pilot said with a smile.

At this time, the captain came over and angrily asked the co-pilot to shut up. And got into the cockpit and asked to take control of the plane.

Liu Yiling had a lot of thoughts in his mind, and there was a problem with liquid nitrogen. Four large canisters are enough for thirty-six liters, which is not quite the same as the previous one.

These words jumped up and down in Liu Yiling's mind, and he also saw the ice in the mouth of the valve.

Thinking of all this, Liu Yiling looked at the four large jars in the distance, all of which were wrapped in plastic seals. And inside the plastic package should be the real bottle, Liu Yiling at this time subconsciously shouted: "Who has a sharp object such as a knife to lend me." ”
